ABSTRACT:
Electrical devices comprise a conductive polymer element and, in electrical contact therewith, a flame-sprayed layer of a metal or other highly conductive material. Electrical leads can readily be attached to the flame-sprayed layer. Particularly valuable devices are those in which at least part of the conductive polymer element is a PTC or NTC conductive polymer. The flame-sprayed layer can be formed directly by flame-spraying a suitable material onto the device, or by flame-spraying the material onto a carrier and then laminating the layer, on the carrier, to the device.
